Notable: The DeSoto boys are the defending champions, but their 800-meter relay - the nation's fastest - didn't get out of the area meet. That opens the door for area teams Klein Oak, Bush and North Shore, which finished second a year ago. Bush is the only school with all three relays competing. The Bush girls can make a push behind three-time qualifier Rushell Harvey, who is the top seed in the 100 and second in the 200. Returning state champions are College Park's Katie Jensen (3,200), The Woodlands' Katie Willard (800), Langham Creek's Skylar Ross Ransom (100 hurdles) and Alaysh'A, Spring (300 hurdles). Ariel Jones of Atasocita is the top seed in both hurdle races, while Manvel's Meschelle Gills was 4A's 800 champion last year.Class 4A

Notable: Ridge Point's Cameron Burrell is the defending 100-meter champion and returns to the same track where he ran a 10.07. He could add a second gold medal in the long jump. Ridge Point advanced its 400 and 1,600 relays as well. That could be enough to make a push for the team title - five-time defending champion Lancaster only qualified one relay and three individuals. Watch for Summer Creek, which won the Region III-4A title, and Fort Bend Marshall, which tied Ridge Point for third. The Wheatley girls won their first region title and send seven athletes to state, including senior Daye Shon Roberson, a three-time state qualifier. Returning state champions are Friendswood's Ryan Teel (1,600 and 3,200) and Willis' Chris Platt (400).Class 3A

When: Saturday.

Notable: The injury bug finally caught up with the Stafford boys, who won their first region title last year before finishing second at state with a pair of first-place relays. Neither relay got out of the region meet, and only Carlton Anumnu (100 meters) is returning. The Bellville and Navasota boys each qualified two relays and have a third entrant in Aaron Sanders for Bellville (100) and Austin Collins for Navasota (triple jump). Brookshire Royal's Diana Moreno is the defending champion in the 1,600 and 3,200 but doesn't enter as the top seed in either event this year. Watch for Sealy triple jumpers Tyistyn Allen and Kristopher Brown, while fellow Tiger Austin Pratt could pull a double in the shot put and discus.
